I provide information regarding programs that I maintain via
email, UseNet and other media. I usually identify myself using my
name, rather than an alias. For example, depending on the media
(working down from email to account names):

For instance, starting around 2008 UseNet has become less
accessible, and various web forums have largely replaced it. One
drawback to these is that their content is controlled by a few
individuals, who may overtly or silently modify the content and
otherwise control access.

As a result, I am forced to use an alias for these web forums,
with the corresponding user name in parentheses:

Guessing by the webpage's response, it seems that my name has
been added to a list of disallowed usernames. However, there are
numerous names in both forums which are offensive. So that idea
lacks credibility.

Finally, there are a few forums where even that does not allow
me to create an account (apparently rejecting my email address).
My policy on those, is that if I am unable to provide corrected
information, I will not use any information whatsoever from
them.
